Hole saw (bimetal HSS-Co) Abraboro 73 x 38 mm AB30073000

The Abraboro bimetal HSS-Co hole saw 73 x 38 mm is a circular cutting tool designed for making clean round openings with a 73 mm diameter and a cutting depth of 38 mm. Constructed from high-speed alloy steel with cobalt, this hole saw provides enhanced wear resistance and heat tolerance compared with standard HSS designs. It is intended for use with standard arbor holders and adapters and performs on a range of materials including metals, stainless steel, plastics and wood.

Advantages

The bimetal HSS-Co construction combines a flexible backing with hardened cutting edges, delivering a balance of toughness and cutting life. The 73 mm diameter and 38 mm depth accommodate typical installations such as pipe penetrations and cable glands without repeated passes. Teeth geometry and cobalt alloy resist softening at elevated temperatures, reducing edge wear during continuous drilling in metal and stainless steel. The hole saw is compatible with common arbors and adapters, simplifying integration into existing toolsets.

Suitable for

• Creating circular holes for pipe and conduit installations
• Cutting openings for cable glands and electrical fittings
• Drilling through sheet metal and stainless steel panels
• Making holes in plastics and wood for mounting tasks

Key specifications

• Cutting diameter: 73 mm
• Cutting depth: 38 mm
• Material: bimetal high-speed steel with cobalt alloy cutting edge
• Compatibility: fits standard arbors and adapters for hole saws
• Application materials: carbon steel, stainless steel, plastics, wood

How to use

Secure the appropriate arbor or adapter to match the drill and the hole saw's mounting interface. Mark the center point of the hole and, if available, use a pilot drill to guide the hole saw. Operate the drill at a moderate speed and apply steady pressure; avoid excessive feed that could overload the teeth. When cutting metal or stainless steel, use cutting fluid or coolant to prolong tool life and reduce heat. After completing the cut, remove burrs as required and inspect the saw and arbor for wear before the next use.

Usage recommendations

For best performance on stainless steel and hard metals, use a suitable cutting fluid and lower drilling speeds. Periodically clear chips from the cut to maintain efficient cutting and prevent overheating. Replace the hole saw when teeth show significant wear or damage to ensure accurate hole dimensions.
